Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. ... In reaction, a thrusting force is produced in the opposite direction.
Explanation:
After one half-life, 8 g of radioactive isotope will remain in the sample.
<h3>What is radioactivity?</h3>
The act of producing radiation spontaneously is known as radioactivity. This is accomplished by an unstable atomic nucleus that want to give up some energy in order to move to a more stable form.
The following formula is used to compute the number of half lives elapsed:
Hence,8 gram of radioactive isotope remains in the sample after 1 half-life.

Answer:
I would say your answer is: The frequency of oscillations is 1 HZ { 1 cycle per second}.
548kj because The energy in joules of a single photon of wavelength λ in meters is:
E = hc/λ
(6.63x10^-34 J·s) (3x10^8 m/s) / (655 nm) (1x10^-9 m/nm) = 3.03x10^-19 J.
The energy in kilojoules of 3 moles of photons of this wavelength is:
(3.03x10^-19 J) (6.02x10^23 /mol) (3.0 mol) / (1000 J/kJ) = 548 kJ
